Patented Mar. 10,1914.-

' Application filed February 13, 1913. Serial No. 748,219.

To all whom, it may concern:

Be it knownthat I, JUAN Gr. HOLGUIN BURBOA, a citizen of the Republic ofMexico, residing at Hermosillo, in the county of Hermosillo and State ofSonora, Mexico, have invented a new and useful Type-Writing Machine, ofwhich the following is a specification. 1 a

The present invention relates to improvements in typewriting machines,the primary object of the present invention being the provision of amachine so constructed and arranged as to permit of the operationthereof to record eoincidently with speech without the necessity oftranscribing, the construction permitting the writing of a single or aplurality of letters simultaneously, there being provided a plurality ofcases of type keys, each case of-which is constructed to engage theplaten and its individual presentation spaced thereupon so that the onetype of one case will not interfere with the type of the other case.

A further object of the present invention is the provision of keys sodisposed as to be comfortably manipulated by both hands of the operator,there being preferably three series of keys to each hand and six keys toa series, while to provide extra means for operating the differentmechanisms of the typewriting machine, wrist actuated keys are alsoprovided one for each hand.

A still further object of the present invention is the provision ofmeans controlled by one key or any combination of keys,

less than the number of letters of the alpha bet, as for instance, sixkeys, a full alphabet may be controlled and actuated, the

combination of the respective keys or a s1n-- gle ke of each seriesoperating the distribevice or in. other words, the selector which willcause the proper actuation of the selected ke to type presentationposition upon the aten.

A still fhrther object of the present invention is the provision of aplurality of so lectors one to each hand set of keys and one to eachwrist set of keys, a fourth selector being provided and controlledthrough the various combinations of both finger actuated sets of keys toperform various operations asregardsthe spacing of the platen,

- the rotation thereof and the movement during the writing of the typeor the return of the carriage to initial pos tion.

inatieally In. general, the present typewriting machine, consists of keyand wrist actuated lTlBELIISWhQIQbY the various types of, the differentcases are placed in platen engaging posltlon to cause the presentationthereto of a single type or in the present instance, fouritype, so thatshort words, portions of words, or abbreviations may be writtensimultaneously, there being provided automatic spacing mechanismscontrolled due to the number of type actuated so that the platen will berotated the necessary number of spaces for resenting, in typepresentation position, a c eansheet. The rotary platen is so mounted asto be moved normally vertical from the top to the bottom of the page bythe spring actuating mechanism, the same being returned from the top tothe bottom of the page for the new page by an autoactuated mechanism andagainst the tension of a spring. The platen also retates in the samesense when line writing and when beginning a new line, The paper whichreceives the upper end of the type is disposed within the hollow platenand wound from'one reel to another so that the action of the paper fromone page to another is controlled from the key board and automaticallystopped at the desired point so that at the instant of the movement ofthe platen from its uppermost to its lowermost position, a new sheet ofpaper to constitute a new page will be placed upon the platen in aposition for receiving the beginning of the new page. Other means forlimiting the marginal position of the platen and for tabulating isprovided, the same being controlled from the key board. A back spacingdevice is also provided in connection with the marginal device so thatthe platen may be moved rearwardly the desired number of spaces for backspacing.

The control for the present typewriting machine is preferably pneumatic,but it is evident as will presently appear that the pneumatic devicesmay be dis laced and electro magnets controlled thougi any form ofgenerator or battery may be provided.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made with in thescope'of what is claimed without departing from the spirit of theinvention.

In describing thepresent invention, the various mechanisms will be takenup in turn and under the following sub-topicsz' The frame and mainmotor; type basket and control mechanism; platen and carriage; platenspacing and back spacing mechanism; paper control; ribbon mechanism;marginal stop and tabulator device; type basket actuating mechanism; and'signal device. 1

Frame and main m0tor.-Refer;ging to the drawings, the numeralldesignates the frame and easing, said casing being provided with theforward extension at the lower edge thereof provided with the op.-positely inclined faces 3 and 4 which provide a comfortable support forthe respective left and right hands of the operator who sits to face thecasing with his left hand upon the inclined portion 3 and the right'hand upon the inclined portion 4. Provided in the front of the casingis the aperture 5, whereby the various type bars, as will presentlyappear, may be readily had access to for cleaning and also whereby thevisible writingupon the platen 13 may be readily seen at a glance.'

The upper forwardend of the casing 1 is cut away seat 7, while theextreme rear portion .is cut away, as at 6, to provide for 5 thenecessary movement of the vertically movable platen 18, the detail ofwhich will be set forth later on. Mounted in-the rearof the casing, asclearly shown in Figs. 2

and 3 are the two pneumatic motors 8 and 8, 10'

each one of which is actuated by the re .spective feet of the operatorthrough the flexible connections 9, each of which is disposed overthetwo pulleys 10 and 11 and is connected below the casing to a treadle(not 5 shown).

By this means the respective motors 8 and 8 are operated alternately andbeing of a similar structure to the pneumatic structures used inconnection with piano players and other suction machines, will 120automatically operate to create the necessary vacuum within the vacuumchamber 12 Whichis also supported, and carried withinthe'casin 1 Type'lheplaten 13is mounted for movement vertically up and down at the rear0. the machine, and'the detail of such actuating mechanism will be setforth later on, while the type basket which as shown in Fig. 12, is 130as7cet and controlmechanism.

composed of the respective sections A, B, C and D, the sections B, C andD being station: ary and disposed within the are of a circle so that therespective type bars will be properly presented, while the type bars ofthe section A constitute a movable section, the construction of whichwill beset forth later on, and is controlled to present a single type ata time, when desired.

Each type bar of the respective cases, is controlled and constructed asshown in Fig. 8, the type bar 14 being pivotally mounted in thesupporting means 15, and having its short arm 16 connected by a link 17,whose other end is connected to the movable section 18 of the bellows19, the same constituting a vacuum actuated motor for actuating thetypebar 14 to present its type 14 in type presentation position upon theplaten 13.

In the machine herein. illustrated, each of the respective, sections A,B, G and D of the type basket are controlled by the various selectordevices20, 20, 20 and 20, these devices hereinas described and known asa selector, and all of which are constructed similarly, so that thedescription of one will suffice for the description for all.

The detail structure of the selector is clearly shown in Figs. 7 8, 9, 8and 9, and consists primarily of the lower disk 21 which constitutes avacuum chamber 22, as clearly illustrated in Fig. 8. This chamber 22 hasa nipple 23 which has connected thereto the flexible tubing 24 led fromthe vacuum chamber 12, and as said vacuum chamber 12 is, as beforestated, connected to the respective motors 8-8, the vacuum is createdtherewithin and consequently through the tube 24 in the chamber 22. Thischamber 22 is provided with a plurality of ports or ducts 25 and alsohas rigidly connected thereto, the outer disk 26, which conpresentationof the selected type 14.

stitutes with the disk 21, the supporting medium for the plurality ofoscillatory disks a, b, 0, (Z, c and f. The outer disk 26, as clearlyshown, is provided with a plurality of ports 26, whose mouths each haveconnected therein the nipple 27, said nipple 27 having led thereawayfrom the tube 28, which provides a means whereby the vacuum effectproduced, as will presently appear, will actuate its selected motor 19to cause the The various oscillatory disks or rings as a, are mountedproperly for individual movement between thedisks 21 and 26, and each ispro-.

vided with a plurality of apertures 53 and exhaust ports 54;, theapertures 53 being disposed to be placed in registration with therespective apertures 53 of the adjacent oscillatory disks so" as toprovide, by the action of the disk, as f, Fig. 8, or by the combinedaction of two or more of the disks as a,registering"conduits from. oneof the ports 25 of the vacuum casing 22 to one of the ports 26 of theplate 26, this action causing the diaphragm 45 carried by the support l3and having the casing 14,- to be inwardly flexed to actuate the valvestem 46 carrying the valve 17 and against the spring l8, opening theport of the casing 21 and closing the exhaust 01' outlet port 50, all

clearly shown in Figs. 8 and 8. This action will direct the vacuumeffect from the chamber 12 through the tube 51 which is connected tonipple 52 of the casing 21 to operate the selected motor 19 and causethe proper presentation of the type 14:. Upon the non-registration ofthe selected disk (1,

i b, (I, (Z, c or f, or any combination of them so as to cause theintersecting of any of the channels formed by the various ports 25, 53and 26, the valve stem 46 \Vlll be released due to the suction actionupon the diaphragm 45 being released, so that the spring 48 will movethe valve 17 to openthe port 50 and close the port of the chamber 21,

this action permitting the spring of the motor 19, due to the opening ofthe port 50 to the atmosphere, to assume its'expanded position so thatthe type bar 14 will be moved to its normal position. The type bars maybe constructed to be returned by springs or by.gravity and still bewithin the scope of the present invention.

In order that the respective oscillatory disks such as a may be operatedselectively to produce the desired combination and operate the selectedtype bar 14, or cause the actuation of the desired mechanisms aswillpresently appear, each disk is provided with an 'aperturcd arm or lug29, projecting radially therefrom and connected by a link 30 to the freeend of a link 31,. the link 31 being pivotally mounted at its other endto a fixed support 32 disposed conveniently with relation to itsrespective selector. Led from the connection between the two links 30and 31 is an operating means 33, which may be a flexible cord or any rodwhich carries thereupon the disk 35 to coact with the stationary disk 34to extend the spring 36 so that the oscillatory disk may be returned toits normal position upon the release of the manually controlledselecting key 39-39 or 39. The detail of this struc ture is clearlyshown in Figs. 8, 9 and 26, the connection 33 being preferably connectedto an arm- 37 of a bail 38 for operating the respective selectors 20 and20' or to a lever 42 foroscillating the disks of the sc lector 20. Therespective levers 4-2 are controlled through the laterally disposed le-.of these levers 4O toieach right and left hand, and there arepreferably as illustrated Q at'the left in Fig. 3, six keys39, whichcon-' stitute the disk control of the oscillatory 5 disks of therespective selectors and 20, which as will presently appear controlprimarily the actuation'of the various type bars 14 of the differentcases of type.

By the arrangement and construction of the various key levers 38, 39 and40, in combination with the connections 33 'and levers 42, differentcombinations are effected by the use of one key or any number of keystherewith to cause the, desired oscillation of the respective disks 0:,b, 0, 3, e and f, 'ofthe respective selectors 20 20 so that the "se-jlected type bar will be actuated to present the type at the desiredpoint upon the paper upon the platen 13. ,AS for instance, the actuationof the single or any combination of the keys 39, at the left hand sideof the machine will actuate the selected disk or disks of the "selector20, which in turn through the respective selected motor 19- controlledthereby, will actuate the selected [type'of the sectional and slidablesection AL. of the basket, so that its type will be presented upon theplaten 13,-at the extremeleft as viewed in the diagram Fig. 12. Each oneof the respective type bars of the section A carries preferably threetype, an upper and lower case consisting of the small and capitalletters and the various marks used, as

a colon, semi-colon and accenting marks.

This section A, as will presently appear, is' moved to present eitherone of the respective types to the platen, the small letters beingpositioned to coact in combination with the single type of the vario iistype bars of thesections or cases 13, C and D so that under ordinaryconditions one type of. eachv r case may be operated to present fourtypes simultaneously to the presentation point 0 the platen 13. Whena'capital letter is used of the case A, only the type of, the cases B-and C can be used while Where a third type is used only the type of Dcan be used, the reason of this being clearly apparent from thedescription to follow lat'eron.

. In the same manner as the individual keys of.a set ofikeys 39f39' or39*, can be combined to writ-e one letter of the first or second caseAB, at the same time, by advanc ing some fingers. 'morethan theothers,the sets of keys 39, 39' and 39 can be combined, and a. combination ofthem, by. means of the levers 4042,: through the selector 20, regis-'tors a letter of the third case 0, simultaneously with those of-casesAB.

' The selector 20 consists only of two disks a-b and is used as aspacing selector, or for causing the writing of usuallyv the mostfrequent letters of the alphabet, as for in stance, e and .9. Theserespective disks a and b ,are controlled through the flexible percross-bar 59, each of the rods 58 being connections 33-33 operated bythe respective disk actuatedkey levers 55-55 disposed at the forwardcorners of the inclined portions 3 and 4 of the casing and directlybelow each of the respective left and right wrist-s of the operator. 7

Platen and carriage.The platen 13 is disposed for vertical movementinstead of the usual horizontal movement for producing writing, upon thetop to the bottom of the page, while. the same is rotated horizontallyduring the writing of a line, the-same being actuated a space ora numberof spaces I at a time according to the number of type that are presentedto the platen through the actuation of the keys and .combinationsthereof. A lower cross-bar 67 is connected by means of. the two verticalrods 58 to the up movable and journaled for vertical sliding movementwithin the stationary or fixed tubes 6O mounted properly within thecasing, the axis 61 oftheplaten 13 being j0ur naled in the cross-bars57and 59 for-rotation while the bars or rods 58are mounted within. thetubesGO for vertical movement, the said' rods'58 and cross-bars'57 and59. constituting the carriage for the platen and bodily movablevertically.

' 9 In order to" produce the necessary hori- 5 zontal rotation of theplaten 13 to. present a new space. for the presentation of a typethereto, after the actuation of the type bar controlling keys of themachine, the motors 62'and 63, which are of the suction bellows type,areprovide'd, and have'their control through the vacuum chamber 12, andthe se- 1 lector 20, one of the levers 42 being the ontrol therefor, "sothat these motors 62-63 will be operated to operate the crank shaft .64which is journaled in the respective bearf ings 65, and 66. As clearlyshown in Fig.2,-

there is keyed upon the crank shaft 64, a, gear 67, which under normalconditions is in mesh with the gear 68 carried upon the lower end of theoscillatory and rotatable shaft 69, this shaft 69 being. journaledwithin the swiveled or swinging-block .70 disposed between the spacedarms 71' of the 1 supportinglugs 72. The supporting lugs 7 are securedto one of the tubular supports 60 which constitutes one of the carriageguides.-

Theshaft 69 being thus rotated, rotates the upper gear 73, wl'nch is atthat time in mesh with the gear 74 upon the lower end of the verticalshaft 7 5', this vertical shaft 75 ha'v-' ing keyed upon it theintermediate gear 76 for actuating the escapelnent 82, as will presentlyappear, and the upper gear 77, which constitutes the main operating gearfoiig the rotation of the platen 13, the dial 202', and the marginalcontrol 206, all 31s clearly shown in Fig. .11. I

A gear 78 is in mesh at all times with'the 13( Loeaeeo gear 77 andtransmits motion through the large gear 79 to the long gear 80 which 1sdisposed vertically of the machine and in mesh at all times with thegear 81 connected to the platen 13 and its shaft (31 so that regardlessof the position of the platen relatively to the casing in its verticalup and down movement, the gear 81 will cause the desired rotation of theplaten to present a new space for the presentation thereto of the type.By reason of the fact that the lever .12 with the selector 20 foractuating the motors G2 and 63 are operated at all times through one ofthe levers 40 controlled by any one of the keys 39, 39 or 39, the platen13 will be rotated one space for each type, but should four type bepresented as illustrated in Fig. 12, the motors G2 and ($3 will berotated to impart to the platen 13 a movement equal to five spaces whichconstitute the four spaces for each type and the extra space between thetype for the next space to be printed.

In order to provide a means for indicating at a glance the position ofthe platen relatively to the type line being printed, a gear 200 is inmesh at all times wlth the gear 201 which actuates the dial 202 disposedat the fO1\'t11(l upper edge of the machine and in ready view of theoperator.

The control device for the respective motors 62 and 63 is clearly shownin Figs. 18, 14, 15, 1G, 17 and 18, and includes the two stationaryplates 301 and 302 which have mounted for oscillation therebetween, thecontrolling rotatory disk 303, the tubes being led from the vacuumchamber 12 to the ports of the disk 301 and to the motors 62 and 63through the respective tubes 62 and 62 and 63 and 63 to the disk 80.2,the rotatory disk 303 being provided with the recessed portion, asclearly shown in Fig. 17, so as to cause the inter-linking orintercommunication between the respective tubes 02 or (32", or 63' or 63to impart the necessary action to the movable bellows of the motors 62and 63, respectively, and consequently cause the desired act-nation ofthe shaft 64:.

In order to operate the platen carriage to impart. to it the necessaryupward vertical movement, due to the line spacing and also to impart toit the descending vertical movement during the change from a writtenpage to a new page, the shaft 69 must be swung so as to disengage thegear 73 from the a gear Hand the gear 68 from the gear (37, this beingeffected through the motor 83, controlled through the selector 20, saidn10- tor 88 being oymrziblyconnected to the bell crank lever 8-1 whichis connected to the sliding block85 mounted upon the twopositioning ofthe gear, 87 into mesh with the gear 88, so that the shaft 69 is rotatedto actuate the gmr 89, and as the bevel gear 89 is placed in mesh withthe bevel gear 90, the shaft 91 journaled in the bearings 92 andcarrying thegcar or pinion 93 is retated. This rotation controls themotion to the toothed rack 941 of the platen carriage, said rack beingdisposed between the crossbars 57 and 59, and causes the platen carriageto be elevated the desired spaces, as for instance, one line, two linesor three lines, or will cause movement downwardly of the platen 13 fromits highest to its lowest point upon the presentation of a new page andagainst the tension of the carriage actijlatingspring 50 (Fig. 11) whichis of usual construction and is connected to normally elevate thecarriage.

The escapement mechanism for permitting the movement of the carriage andplaten due to the shifting from one line to the next and for varyingspaces as for instance one, two and three spaces, consists of thetoothed rack 93 carried at the opposite side of the platen to the rack94, the same having in mesh therewith at all times the gear 96 carriedupon the swinging shaft 96, the block 97 being constructed and arrangedaccording to the sliding block for swinging the shaft and placing thegear 96 into and out of engagement with the rack according to theactuation of the motor 99 and consequently the desired spacing required.The block 100 is the swingingly journaled block for the shaft 96, whilethe escapement 101, shown at the right in Fig. 2 and which isconstructed similarly to the cscapement 82, is provided for actuatingthe. shaft 96 or rather controlling the actuation thereof to permit themovement of the platen and carriage the desired and selected spacingdistance from one line to the next.

In order to permit the upward and downfixed to the frame of the machineso as to provide a rigid support therefor.

Platen spacing and back spacing mechanism.-In order that the platen, asbefore described, may be rotated a single space or up to five spaces inthe present instance, an

These two stops are adjustably ,mounted upon the guide rod 106 which isescapement device, as clearly illustrated in Figs. 19, 20 and 21 isprovided, this escape- -ment device also being similar to the devicc=101 for controlling the vertical movement of the platen carriage, bothof such devices being constructed for control from the key board andthrough the vacuum chamber 12.

The gear 7 6 in this instance as before stated, is geared to therotatable casing 82 of the escapement device 82 and this casing isprovided with the teeth 107 and the facial pins lug 113 being connectedto one end of the carriage and having fast thereto, a pin 114,

which forms a journal for the points 115 of the respective toothengaging fingers 116,

117 and 118, there being a single finger 116 formed integral with thelug 113, a plurality of four intermediate fingers117, and a singleflexible finger 118. This finger 118 is provided with the flexing end119, which is normally, held coextensive with the main body of thefinger 118 by means of the spring 120. Each of the respective fingers118 and 117 are provided with a pin 121, which overlaps the adjacentfinger, as clearly shown in Fig. 20, so that the fixed finger 116 limitsthe movement of the respective fingers in the direction of'the arrowFig. 19 and consequently in a position'for engaging the teeth 107 tolock the disk 82 against, rotation. The springs119 are connected to thelugs 118 of the Various movable fingers 117 and 118 to form a resilientmeans for permitting the back stepping or back spacing of the disk 82and consequently the platen 13 by means-of the back spacing motor 129which is provided with. the flexing arm 130 connected by the pivotinglug 131 to the niovable section 132 of the motor. This operation iscontrolled from the keyboard to back space the disk82 one space asdesired.

In order to-control' the actuation of the carriage 112, the same beingmaintained in its normal position by means of the spring 125, with thefinger 119 in engagement with .one of the teeth 107 to maintain the disk82 in the desired position, and so as to bring one of the respectiveteeth 117 orthe flexing tooth 118 in engagement with one of the teeth107 to permit of the movement of the disk 82 and consequently the platen13 the desired number'of spaces, the flexible connection or cord 122 istrained over the rollers 123 and 124 and has one end connected to thecarriage 112 to move the same against thetension of the spring 125, thisstructure bemg clearly illustrated in Figs.- 20 and 21. This flexibleconnection 122 is connected to'the pivoted bail or lever 126,

carried upon the shaft 127 within the casing,

this bail or lever 126 being operably connected to the controllingmembers of the respective motors 128-, there bemg five of these motorseach of a diflerent' magnitude of movement, so as to control therelative move ments of the lever 126 and consequently the difierence ofpull upon the cord 122 so as to present the selected one of therespective fingers 118, 117 or 116, to its respective tooth 107 ofthedial 82 and thus consequently permit the necessary movement to theplaten 13. By this means, it will-be seen that the actuation of theselector 20*, due to the move ment of any one of the levers 42 willcontrol the actuation of any one of the motors 128, or any numberthereof, so as to properly actuate the lever 126 and the respectivefingers 1 18, 117 and 116, so that the escapement drum 82 willbepermitted to move the desired distance through its motor controls 62and 63 heretofore described.

Paper c0ntr0Z.-In a machine constructed for this character of work, itis desirable that the necessity of removing a finished page from theplaten and the placing of a new page thereupon be dispensed with, and inorder that an automatic means may be pro vided for placing upon thesurface of the platen, at any desired time, a new sheet of paper, andalso provide a means for retaining the succeeding new sheet and also thesheet theretofor'e printed upon, the detail structure as shown in Figs,22 and 23, is designed and employed. In this structure, the .platen 13is hollow and is provided with the longitudinal slot 133 throughone sidethere of while journaled within the platen and substantially the fullwriting surface thereof, is the supply roll 134, and the winding roll136, the paper 135 being led from 'the supply roll 134 through the slot133 around the exterior surface of the platen 13 and through the slot133 to the winding roll 136. To cause the movement of the paper writtenupon and the placing of a new sheet upon the exterior of the platen, amotor device, as

clearly shown in Fig. 23, is provided. In I doing this, the nipple 137is connected by a j flexible tube to the vacuum chamber 12, and

its duct is in communication with the duct 6 138 formed in the rod 58and bridging member- 59 of'the carriage, the other terminal of thechannel or duct 138 being in communication with the duct or channel 139formed in the upper end of the axle 61 of the platen 13. This structureisclearly shown in Fig. 22. Led from the nipple 140, formed upon theaxle 61 is a tube 140', which is in comtions 143 and 144 of said arm 142to the opcrating link 141-5. This link 1 15 is connected to the pawlcarrying arm 14:6, which is disposed to engage the ratchet teeth 1 17normally held. against retrograde movement by the arresting pawl 1418,to thus 'rotate the large gear 149, which is 'in mesh with the smallgear 150 of the roll 13G.

The movement of the arm 1 12 and its pin and slot connection is such asto impart the necessary rotation to the gear 149, for any number thereofthat may be necessary to cause the paper to be moved the proper distanceto wind the type writ-ten page within the platen and upon the roll 136to present a new page upon the surface of the platen' 13. In order toprovide a locking means for the paper while 111 type presentationposit-ion, a flexible cord 151 is connected to the movable member ofthemotor 1 11, passing over the guide pulley 152 and through the springlimiting lug 153 to the brake shoe 154., the spring 155 being sodisposed as to normally exert an outward pressure upon the brake shoe15-1 to wedge the same within the space 133 of the platen and againstthe sheet of paper at such point. It will thus be seen that the initialmovement of the motor 14. 1 will not affect the rotation of the gear 140and consequently the roll 136 until after the cord 151 has been actuatedto remove the brake shoe 154 from engagement with the paper at the slot133, thus allowing ample time for the paper to be released so that theroll 136 may be operated to remove the type written sheet from thesurface of the platen and present thereupon a new sheet.

In. order to provide a pneumatic means for stopping the actuation of themotor 111 when the type written page has been removed within the platenv18, the paper is perforated at intervals, such intervals beingpreferably the distance fromthe slots 156 formed in one wall of the slot133 to the adjacent wall of the slot 133, such perforations being thuspresented at the proper time to the slot 156 of the channel 157. Theslot 156 is extended the full length, or any predetermined distancethroughout the length of the slot 133, the same having its nipple 157engageable with the release side of the valve and control casing J ofthe motor 141.. so as to act in a similar manner to the release of'thevalve 47 of the devices shown in Fig. 8, so that the motor 141 willbeopen to' the air and will thus collapse and be stopped in its actionas regards the rotat'ion ofthe roll 136, the arm 142-being moved in theopposite directionso that the pawl arm 146 will-ride upon the teeth 147without affecting the. movement thereof but to be placed in a positionfor the next succeeding action or page changin In order that envelopsmay be held upon the present platen, the envelop clips E are providedand are connected to the adjacent scale marked flanges F of the platen13, as clearly shown in Fig.

Ribbon meclrwnwz'smr lhe ribbon mechanism and the control therefor isclearly shown in diagram in Fig. 27. the mechanisn'i. for operating theshaft; 168 being shown in Figs. 2 and 11, and. consisting of the motor158, which is controlled at the actuation of any one or any combinationof the keys to properly feed the ribbon 1713 to present a new portionthereof to each type prcsentation, said motor 158 having its movablemember connected through the link 15$) to the bell crank lever 160,whose hooked terminal 1131 is operably connected to the carrying block102 which is constructed similar to the block 85, and provides a meansfor tilting the shaft 163. which is rotatably mounted within the swinginblock 164, as clearly shown in Fig. 2. keyed upon the shaft 163 is agear 11kt, which operates the gear 165. This gear 165 has a pulleyportion over which is trained the endless chain or cord 166, which isoperably connected to the sprocket wheel or pulley 1(17 keyed upon therotatable and slidably mounted shaft- 168, which constitutes theshifting shaft and power transmission shaft of the ribbon mechanism.Keyed upon this shaft 168 are the two bevel pinions 170--171 and themanually controlling crank 169, which as clearly shown in Fig. 1 isdisposed at the upper portion of'the -asing 1 in ready access to theoperator.

A bevel gear 172 is disposed at the lower portion of the casing and iscarried by the shaft 173 which has keyed upon its inner end the ribbonspool 171, the same being provided with thearcuate slot 175 open to theperiphery thereof for the seating therewithin of the ribbon carriedshifting actuating pin 180, there being two pins one adjacent to eachend of the ribbon 17(3 and disposed to assume the \fll'lUllr; positionsas shown in Fig. 27. The shaft 178 is pro vided with a bevel pinion 177disposed to be placed in mcshwith the pinion 170 of the shaft 168, therespective pinions 172 and 177 being disposed to be operated alternatelyto cause the desired shifting of the ribbon as is usual'in type writingmachines. The upper reel 179 is carried by the shaft 178 and isconstructed similarly to the reel 174.

In order to provide a means for shifting the shaft 168 so that theribbon is continuously fed andrevcrscd according to the erable relationto the spool 192 mounted upon and carried by-the shaft 168.

Each of the respective valves 185 and 186 is provided with a port 187,which is dis posed at the proper time due tothe engagement of the pin181 with one of the levers 183*184, to move the valve to assume theposition as shown at the top of Fig. 27, and in registration with thetwo oppositely disposed ports 188 and 188, which are connected to thevacuum chamber 12 and to the motor chambers 189; and 190, in the presentinstance the motor 189 being actuated to properly elevate the shaft 168to disengage the gears 171 -172 and engage the gears 170 and 177 tocausethe ribbon to be fed from the reel 174 upon the reel 179, the partsbeing in the position they as same at the initial registration of theport 187 of the valve 186.

The ribbon as clearly shown in Figs. 1, 8, 4 and 10 is guided throughthe stationary guides 192 carried by the frame of the ma chine or thestationary portion of the type basket support, the same presenting theribbon to all of the four type as illustrated in Fig. 12 sothat fourtype may be printed sitabulator device 204, and also the ribbon end of aline,

Marginal stop and tabular/0r deoic'e.- In order that the platen 13 maybe stopped at any position throughout-the line, as for plain writing, asregulating the margin, or as in tabnlating for bills and the like, agear 208 forms an inter-linking or connectbet'ween the gear 201, thedial 202 and the gear 204' keyed upon and rotating the shaft 205, thisshaft 205 having keyed upon its upper end, the marginal disk 206,clearly shown in detail in Fig. 24. This disk is provided with the mainmarginal or fixed stop 207, and the two adjustable marginal stops 208and 209, the same being adjustably connected. for attachment to theperiphery of the disk 206, so that, as the plates may be through therespective train of gears at anydesired point. p

The means for ordinarily stopping and releasing the platen 13 at thebeginning and comprising either one of the adjustable stops 208-209 andthe fixed stop 207, in combinatiomwith the pivoted motor controland-signaling lever 214, which'is disposed to project between the openspaced ends of the open ring 210 which is permitted a slight slidingmovement and constitutes the tabulator stop carrymg device. Thesigrosaeee naling lever 214 is pivoted at 215 and has its terminalcarrying the valve 217 disposed within the valve casing 216, the samebeing operably the vacuum chamber 12 so that when the stop208 engagestheouter end of the valve connected with the motor 274, and I actuatinglever'214, the valve will move to open the port and permit of theactuation of. the wrist tapping lever 273 (Fig. 3) to signal theoperator thatthe marginal stop 220, must be operated to release theplaten. The stop 220 is mounted inthe-two lugs 219 carried by theopen'ring 210,as clearly shown in detail in Figs. 24 and 25. This stop220 is provided with the long end 221 and with the short end 222 so thatthe short end willengage the ,stop208 during the ro-' tation of the disk206 in the directiomof the arrow Fig. 24, after the engagement of thesame stop 208 with the signal actuating member 214, and themanipulationot a key to cause the actuation of the motor 228 through thelink 223 which causes the marginal stop 220 to disengage the 'arm 222from the'marginal stop 207 to place the long end 221 in the path toengage the stop 209 and thusllock the platen 13 atthe beginning of a newline and simultaneously with the spacing of the carriage to present anew line in type presentation position.

' In order to provide a cushioning means for the oscillatory ring 210when the stops 208 and 209 are in enga ement with the pivoted stop 220,the end 211 which is formed in the shapeof a plunger and enters the aircushion 212, a slight vent aperture 213 being provided to permit theescape of the air and thus provide a pneumatic butter for th platen whenthe stops 208 and 209 have been placed in engagement with the 221 of thepivoted stop 220.

In order to providea means for present- I platen 13 for tabulat-ingpurposes, a plurality of pivoted stops 225 are disposed, as shown inFig. 24, upon the ring 210 and have their stop engaging ends 226disposed to engage the stop 207, of the respective stops 225 beingprovided and being operably through the link 227 as clearly shown inFig. 10. These motors 228 are controlled throughany of the desiredselectors 20, 20, 20 or 20 and the necessary key of the machine. V I

, Type basket actuating .me0ham'sm.-As clearly shown in Figs. 10'and 12,the sectionA ofthe type basket is mounted for ing the thamotor 228 ineach connected thereto sliding movement with relation to the other 28,and thus being shiftable to present a single type, at a time in typepresentation position relatively to the platen. This case of type bareis therefore carried by the sliding plate or frame 229, whose-upper andlower edges respectively are supported be tween the anti-frictionalrollers 230, there being four in this instance, while connected to andcarried by the plate or frame 229 and projecting from one side thereofare the two pins 231 and 232.

Under ordinary conditions, the spring S holds the plate or frame 229 andconsequently the case of type bars A in the separated position, so thatthe small letter will be presented when the keys for actuating thesetype are operated, but should it be desired to present a capital letter,which is the intermediate type upon the respective type bar, a key isactuated and through the se' lector operates the motor 235, whosemovable terminal 233 engages the pin 231 and moves the frame 229 and thetype toward the center of the machine so that the capital letter will bepropelled against the platen.

Should it be desired to place the third character or the one to theextreme left, as shown in Fig. 28, to the platen, the motor iscontrolled in a similar manner through the selector 20 so as to actuatethe movable terminal 234, which engages the pin 232, and as the motor236 is of a greater magnitude and has a greater movement than the motor235, the frame 229 and the section A carried thereby may be moved agreater distance or one space farther toward the center of the machine.Upon the release of the type, the spring S will return the frame 229 toits initial position as shown in Fig. 10.

Signal deoi0e.1n a machine of this character, it is desirable that noaudible signal be provided, therefore in order to notify the operatorwhen the platen is at the end of a line or at the end of a page, somemeans must be provided to attract his attention so that the proper keymay be manipulated for presenting a new line for returning the carriage.This is accomplished by means of the pivoted tapper 273, which ismounted at the forward right hand corner of the casing 1, and insuch aposition as to tap the right wrist ot' the operator whose hands being inthe proper position for manipulating the keys 39-39 and 39 with hiswrist in proper position for engaging the key 55 will be properlynotified that it is time to manipulate thekeys for shifting the platenor the carriage as may be necessary. This pivoted tapper 273 iscontrolled through the motor 274, which is controlled by the pivotedvalve actuating means 214 when either one of the stops 209 is placed inengagement therewith, the nipple connections of the valve casing 216being operably connected to the vacuum chamber 12 and themotor 274, sothat the motor 274: is automatically actuated due to the envgagement ofthe stop 209 with the valve and a portion of a fourth as herein setforth,

and that various other key operated dcvices may be employed to controlthe various motors for actuating the type bars, ro-

tating the platen, moving the carriage to and against the spring controltherefor, and for actuating the ribbon feed.
